Rakes

Rakes combine several measuring heads in one probe and are therefore ideal for measuring flow variables at several measuring points simultaneously. Rakes can be equipped with the following measuring heads:

  • 3-, 4-, 5-, 7-, 14-hole head,
  • Pitot head,
  • keel total pressure head,
  • Kiel total temperature head,
  • Preston Kopf,
  • Prandtl head.

Product Details

By combining different probe heads such as multi-hole, kiel (total pressure and total temperature),preston and pitot heads within a single rake or probe, customers benefit from enhanced spatial resolution. Our innovative additive manufacturing process offers unparalleled geometric flexibility, allowing rakes to be precisely tailored to specific applications or seamlessly integrated into other components while ensuring exceptional mechanical strength.
Vectoflow customises rake designs according to customer specifications, leveraging Finite Element Method (FEM) simulations for optimal performance.
Vectoflow develops the design of the measuring rakes based on customer requirements and supports this with FEM & CFD simulations. Vectoflow also carries out a wide range of tests to determine and verify properties such as roughness, geometric accuracy, crack formation (X-ray or FPI examinations, blue light scan), and natural frequencies (natural frequencies can be controlled by optimizing the internal structure).
The measuring rakes are also calibrated in Vectoflow’s own calibration channels.
